The voting for the talks at Meeting C++ 2018 ended, and the results are in!

Voting results for Meeting C++ 2018

by Jens Weller

From the article:

On Sunday the voting ended for this years conference. And the results are interesting, each talk received between 87 and 104 votes from 147 active voting sessions. In total its 10685 votes casted. So lots of folks did have a look at each talk, the average of the collected votings is then what determines the top talks at the conference...

CppCon 2017: Delegate this! Designing with delegates in modern C++--Alfred Bratterud

By Adrien Hamelin | Jul 11, 2018 01:23 PM | Tags: performance community

Have you registered for CppCon 2018 in September? Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2017 for you to enjoy. Here is today’s feature:

Delegate this! Designing with delegates in modern C++

by Alfred Bratterud

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Designing a fast IP stack from scratch is hard. Using delegates made it all easier for IncludeOS, the open source library operating system written from scratch in modern C++. Our header-only delegates are just as fast as C-style function pointers, compatible with std::function, and allows any object to delegate work to stateful member functions without knowing anything about the class they belong to. We use delegates for everything from routing packets to creating REST endpoints, and most importantly to tie the whole IP stack together. In this talk we’ll show you how we use delegates in IncludeOS, discuss pitfalls and alternatives, and give you all you need to get started.

CppCon 2017: Coroutines: what can't they do?--Toby Allsopp

Coroutines: what can't they do?

by Toby Allsopp

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Coroutines are coming. They're coming for your asynchronous operations. They're coming for your lazy generators. This much we know. But once they're here, will they be satisfied with these offerings? They will not. They will require feeding, lest they devour our very souls. We present some fun ways to keep their incessant hunger at bay. I, for one, welcome our new coroutine overlords.

The Coroutines Technical Specification is an experimental extension to the C++ language that allows functions to be suspended and resumed, with the primary aim of simplifying code that invokes asynchronous operations. We present a short introduction to Coroutines followed by some possibly non-obvious ways they can help to simplify your code.

Have you ever wanted to elegantly compose operations that might fail? Coroutines can help. Have you ever wished for a zero-overhead type-erased function wrapper? Coroutines can help. We show you how and more.

CppCon 2017: Agent based class design--Odin Holmes

Agent based class design

by Odin Holmes

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Abstracting a set of functionalities into a class which provides a higher level interface often requires tough design decisions. Users who do not have the exact requirements for which the abstraction is optimized will suffer a syntactic or run time overhead as a result. Alexandrescu's famous "policy-based design" provides a mechanism to allow the user to extend and customize an existing abstraction in order to fine-tune its functionality for many different use cases. This is however limited to use cases where each policy more or less represents a compile time strategy pattern.

Alas, not everything is a strategy pattern. In this talk I will explore the viability of a more agent-pattern-like paradigm where each policy knows its requirements and publishes its capabilities. In this paradigm, glue code connecting any valid set of policies is automatically generated using template metaprogramming. This allows much more powerful customizations while maintaining static linkage.
